For owners of the Carbon8 Stiker-9 CO2 Blowback pistol, they can upgrade the inner barrel with the PDI Wide Bore 6.1+ Inner Barrel which has a length of 97mm. The CS barrel is a more affordable alternative to their premium SUS barrels. It boasts the largest inner diameter within the CS inner barrel range. While the FPS is lower compared to RAVEN and DELTA, it offers improved flight stability.

The tolerance of the inner diameter has been adjusted from 0.002mm to 0.007mm in comparison to the SUS barrel, making it more cost-effective.

In terms of other dimensional tolerances, the CS barrel maintains the same high quality as the SUS barrel.

Please note that an increase in FPS and range are not directly proportional.

Markings are available either through laser marking or engraving, depending on the batch.

Due to the material properties, there may be instances where fine wrinkles appear inside, but tests have confirmed that this does not impact performance.

In rare cases, a thin striped pattern may be visible on the inner surface. However, this does not affect performance and can be removed with cleaning.

Specifications:

• Outer diameter: 8.55mm
